1.1 These requirements cover self-contained drinking-water coolers which employ hermetic refrigerantmotor-compressors and which are designed for connection to alternating-current circuits rated not greaterthan 600 volts in accordance with the National Electrical Code, NFPA 70. The requirements also apply towater coolers which supply both hot and cold water.1.2 These requirements do not include additional requirements applicable to equipment designed for usein hazardous locations as defined in the National Electrical Code, NFPA 70.1.3 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.
These requirements cover inverters ,converters ,charge controllers ,and output controllers intended for use in stand-alone(not grid connected) or utility-interactive (grid-connected) power systems .Utility-interactive inverters and converters are intended to be installed in parallel with an electric supply system or an electric utility to supply common loads.
This European Standard specifies requirements and gives recommendations for the installation of potable water installations within buildings and for pipework outside buildings but within the premises in accordance with EN 806-1.This European Standard is applicable to new installations, alterations and repairs.
This standard applies primarily to copper alloy stopvalves, dimensions DN 10 to DN 100, for potable water supply in buildings up to PN 10 and a distribution temperature of 65℃. Occasional excursions up to 95℃ are permitted for a period of 1 h maximum.
This document specifies the requirements for the installation and commissioning of water-based heating systems in buildings with a maximum operating temperature of 110 oC and a maximum operating pressure of 6 bar.This document covers the system's requirements for the installation and commissioning of individual components of the system (e.g. heat generators, pumps, controls). It does not cover the specific commissioning requirements for these components.This document does not cover the installation or commissioning of attached systems (e.g. air conditioning, domestic hot water or ventilation systems).This document covers only the technical requirements, and
La présente Norme européenne spécifie les dimensions, les matériaux et les exigences de performance (y compris les méthodes d'essai) pour les vannes mélangeuses en ligne d'alimentation en eau chaude, pour systèmes d'eau chaude sanitaire, de dimensions nominales allant de DN 15 à DN 50. Les vannes mélangeuses réduisent la température de l'eau chaude sanitaire avant sa distribution dans le système d'eau chaude. Les conditions d'utilisation sont spécifiées dans le Tableau 1.Les vannes sont destinées à une utilisation avec des chauffe-eau à accumulation, afin de fournir de l'eau chaude tempérée au branchement terminal. Elles ne sont pas destinées à contr?ler la température au point d'utilisation. Les vannes mélangeuses contr?lent la température de distribution à partir d'un chauffe-eau à une valeur prédéfinie ou dans une plage réglable, cette valeur ou cette plage étant situées entre 45 oC et 65 oC.
This standard specifies the characteristics of the materials and the design, the mechanical, hydraulic and acoustic requirements and the test method for copper alloy stop valves, dimensions DN 10 to DN 80 for potable water supply in buildings up to PN 10 and a distribution temperature of 65 ?C.
This draft standard describes the code of practice for planning and construction of drinking water systems in houses and properties as well as the components, apparatus and materials which are to use. It supplements DIN EN 806-2 and gives additional specifications considering national laws, regulations and German Technical Rules.
The standard applies to straight pattern piston type gate valves with bonnet vertical to the pipe axis, with or without drain which are used as stop valves for drinking water supplies in compliance with the standards of the DIN 1988 series and DIN EN 806 series.
The document specifies in connection with DIN EN 1213 dimensions, requirements and tests for oblique bonnet globe valves for nominal sizes DN 15 to DN 80 and up to PN 10 for domestic water supply.
The document specifies in connection to DIN EN 1213 dimensions, requirements and tests for straight pattern globe valves for nominal sizes DN 10 to DN 80 and up to PN 10 for domestic water supply.#,,#
This standard specifies requirements and tests for manually operated piston type gate valves, stopvalves for tapping valves, gate valves and diaphragm valves of special design which are not included in DIN EN 1213 up to nominal size DN 100 and up to PN 10 for domestic water supply.
This standard specifies the installation and design of oil firing systems with automatic, partly automatic and manually operated oil burners as well their oil supply systems for the fuel EL according DIN 51603-1 for all room installations.#,,#
The standard shall be used for fuel gas valves in laboratories. The standard defines types, dimensions, materials and requirements and tests for construction, leak tightness and stability as well as marking of laboratory fuel gas valves for a nominal pressure up to 0,02 MPa (0,2 bar) and a max. temperature up to 60 Grad C.
